Hi Giovanni (and Toby, of course!)
my superficial reading of the draft suggests me that Rease is defined in
terms of RDFa. Ie, conceptually, an XHTML+Rease document (or even
XHTML+RDFa+Rease document) is transformed into XHTML+RDFa. Actually, a
way of implementing it (my RDFa implementor's mind starts working:-)
would be to add a pre-processor (like the hGRDDL idea of Ben) to an RDFa
processor and let the trickier aspects of RDFa be solved by an existing
processor.
Toby, is this the idea? If not, I believe it should be:-)
I have one technical comment, though. The CSS Working group has already
published a CSS3 Namespace Module:
http://www.w3.org/TR/css3-namespace/
which uses a slightly different syntax than Rease for a similar concept.
I think it would be way better to align Rease to this. One could expect
that CSS parsers of the future would include this namespace facility,
which might greatly facilitate the task of Rease implementers...
